SIGMUND HONIG, OF NEW YORK, N. Y

RAZOR-SHARPENER.

Application filed October 18, 1912. Serial No. 726.4 12.

To all whom it may concern Be it known that I, SIGMUND Home, a

citizen of the United States, and resident of the city of New York, in the county of New York and State of New York,- have invented certain new and useful Improvements in Razor-Sharpeners, of which the following is a specification.

This invention relates to improvements in 'azor sharpeners and is more especially designed for honing and stropping razor blades for safety razors.

The primary object of the invention is the provision of an inexpensive machine capable of holding any manner of razor or razor blade in conjunction With honing and stropping surfaces readily manipulated thereon by the operator.

lVhile the main object of the device is to provide a machine in which any razor blade may be readily inserted for sharpening and one in which the honing and stropping operation is accomplished thereby, it is also designed to provide a. holding means for positioning either side of the blade so that it may be operated upon by separate honing and stropping means, which latter are automatically shifted into and out of operative positions.

A simple and inexpensive machine is provided .in which a razor blade is insertedand upon the turning of a crank a plurality of honing and stropping rollers are set in motion which are automatically brought into contact with the blade in succession.

lVith these objects in view and others that will appear as the nature of the invention is better understood, the same consists in the. novel combination and arrangement oi parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

in the drawings forming' a part of this application and in which like numerals of rel'crcncc designate corresponding parts throughout the several \l *-\\".\Z'llf flll'(! 1 is a central vertical sectional view of the device with a safely razor blade positioned therein.

upon lino 5-5, Fig. 3, and-Fig. (S is a detail view oi the adjustable locking means.

Referring more in detail to the drawings, the upright supports '10 oppositely arranged are adapted for journaling the crank shaft 11 operable by the handle 12 and upon which by means of the screw 13 there is rigidly-secured the internal gear wheel 14 having the teeth 15.

Loosely journaled upon the shaft 11 is positioned the spool 16 with the end disks 17, 18 and in which are journaledsharpening and polishing rollers 19. Said rollers 19 are capable of revolving individually,

this motion being effected by a gear 20 snp' plied upon the projecting end' of each roller adjacent the spool end 18, each of said gears being constantly in mesh with the inner .raek teeth 15. The coarseness and formation of the rollers 19 may be such as is desirable for use in connection with what-- ever blades are desired to be sharpened, for instance one of said rollers may be a honing stone and the other three rollers herein illustrated constructed as stropping and smoothing blades of difi erent degrees of softness, and while four rollers are herein shown, it is obvious that a greater or smaller number may be employed.

opposite block E36 is longitudinally movable 'l'or clrinping the blade under adjustment of inc set screw 27. This positioning oi the blade is well illustrated in Fig l, it being evident that the partsv employed are ol' su h proportions as to allow the blade to be. conlaclcd by the rollers \vliilc parallel project; inf; arms 28 carried by the cross piccc are i -"w'ided with shitlable weight mcmhcr:-= t3! whcrcby the degree ol frictional contact oi t blade with the rollers isaccnratcly "cg-- ulalcd. Further, the. cross piece is partially rotatable so that the blade may be -tionedupon said gear 35 positioned With either face thereof adjacent the rollers. The stationary block 25 is preferably divided as best shown in Fig. 4. to provide an interrupted portion 25 adapted to receive the tang of a razor blade of the ordinary construction while it will be evident that in using the wafer blades of safety razors such blades will be clamped between the adjacent faces of the blocks as shown in Fig. l.

The operation of thedevice as above ex,- plained will be evident. By turnii'ig the shaft ll the internal rack 14: is revolved whereby the gears 20 mesh therewith and .are all Slll'lllllttllQUllSly turned to propel each of the rollers, the one only in the position contacting the blade 24:.

The spool end 17 is provided between each twoof'the rollers with two slots 30 adapted to register with and receive the prongs Bl which project either side of the adjacent supporting member 10 and are carried by the rocking lever- 32 pivoted at 33 to the said support. It will be evident that by depressing-the free end of said lever 32 the prongs 3l will be removed from said slots and the spool thereby released and then turned by the turning of the shaft 11 until the prongs again lock the same.

A gear 35 preferably having about 20 teeth upon its periphery is journaled upon the stub shaft 36 of the support and is turned by a one cog proper pinion 37 upon the free end of the shaft 11. One or more adjustable cam engaging devices 38 are posiso placed as to contact the sloping sides ill of the freernd of the lever 32 whereby a turning of the wheel 35 results in engaging said lever end by each of paid members 38 upon iach revolution thereof. An expansion spring -ll retains the lever end having the sides Ill, in an elevated position with the prongs ill in normal lockingengagement with the spool.

In the operation of the device a turning of the handle 12 results. in rotating the roller upon the blade and upon each turn of the shaft 11 and its pinion 87 the gear 35 is shifted one cog so that upon a prcde'- termined number of turns of'the handle one of the engaging devices 38 will depress the lever end 3%, thus unlocking the spool which Will thereupon rotate until stopped by the engaging prongs 31, which latter thereby lock the spool with the next succeeding roller in position to engage and act upon the razor blade. A continuous turning of the handle 12 therefore successively brings all the rollers in contact with the blade for performing their successive work thereon of sharpening and polishing.

As noted in Fig. 5 the engaging members 38 are adjustable and may be mounted in bushings 25$) retained by the winged nuts 40.
